Does 15 Ethanol Damage Car Engines

Ethanol is a type of alcohol that is made from agricultural products like corn. It’s often used in gasoline because it’s a more efficient fuel than regular gasoline. However, some people worry that ethanol may damage car engines.

In this article, we’ll take a look at the research on this topic and see what the verdict is. We’ll also provide some tips for avoiding any damage to your car engine that may be caused by using ethanol.

What is Ethanol and What does it do to a Car Engine?

Ethanol is a type of alcohol that is often used to fuel cars and trucks. It is made from natural gas and plants. Ethanol is a liquid at room temperature, but it can also be a gas when it’s in the engine.

When ethanol is used as fuel, it replaces gasoline. For example, if you put 10 gallons of gasoline into your car, you would put 1 gallon of ethanol into the car as well. The ethanol will help to power the car and replace some of the gasoline that was used to run the engine.

However, there are some things that ethanol cannot do. For example, ethanol doesn’t work very well as a fuel in engines that use piston engines. These engines use pistons to push down on fuel and air to create power. Ethanol doesn’t work well in these types of engines because it doesn’t have a high enough octane rating.

Overall, using ethanol as a fuel does not damage car engines. However, there are some things that it cannot do, so make sure you know what your car’s engine can handle before using this type of fuel.
